Well heck...Brake Booster went out

[ThreeJs]

Couple of months ago..transfer case went out.....

NOW....

About a week ago I had to do a hard emergency stop in traffic due to an accident ahead and lookie-loos.
Yesterday, on the way to work, I had one issue with a hard brake pedal, rapid deceleration for a quick light.
Drove home this afternoon and the booster developed a hiss when depressing the pedal.
Light braking it seems to be working fine. Depress the pedal quickly and harder and I lose boost assist and get a very hard pedal with increased braking distance.

That's the backstory....

I'm going to pick up a booster this weekend probably. Pretty sure I'll be able to shift the master cylinder over enough to get the booster out.
Any tips for removing?

Disconnect the MC and move it out of your way. Booster is bolted to the firewall with 4 studs and attached to the brake pedal linkage. Straight forward job, Nothing tricky.

Pretty much self explanatory.
Disconnect the vacuum hose from booster.
Remove 9/16" (14mm) nuts holding master cylinder. Inner mount stud has two nuts (One for bracket/One for M/C.)
Move master cylinder off to side.
Under dash. Remove clip for brake switch and remove switch at the same time disconnecting the rod for brake booster.
Unbolt four 1/2"(13mm) holding booster to firewall
Maneuver booster out of engine bay.
